Chiral artificial nanosystems constructed from inorganic nanoparticles brought about a paradigm shift in chiral sensing, enantioselective catalysis, chiral polarization engineering, and chiral emission due to their strong light–matter interaction and their precisely engineered properties. Especially bottom-up approaches hold great potential for the inexpensive, scalable production of plasmonic, excitonic, and upconversion chiral materials. This perspective first reviews the state-of-the-art fabrication schemes: chiral molecule-induced chirality, chiral nanoparticle growth, and assembly of chiral superstructures from achiral building blocks. Next, the emerging field of dynamically tunable chiroptical materials, promising for adaptive thin-film optics, display technologies, and information encoding, is explored. Here, the strength of chiral assemblies based on their rich tuning mechanisms and their ability for geometrical reconfiguration is highlighted. Finally, promising future directions and opportunities in the field of active chiroptical materials are discussed.
